NORSOK R-004, rev. 2 37-1A-NHT-P52-00008, rev. 01M Ormen Lange Insulation Handbook 37-1A-AK-R15-00003, rev. 04I Insulation Requirements, Guideline
3. ABBREVIATIONS SS - Stainless steel AL - Aluminium
4. GENERAL All insulation is to be done in accordance with documents referred to in chpt. 2. Close attention is to be paid, so that the applied coating is not damaged. The insulation material build up and thickness are based on NORSOK R-004, NHT-M50-02037, design calculations and experience from previous projects. The specific requirements for the materials to be used are given in NORSOK R-004. The extent of insulation is defined by the process discipline with input from others, such as the safety discipline, and shown on P & IDs. The insulation thickness to be indicated on P & IDs are given in doc. 37-1A-AK-R15-00003. Equipment installed in piping where insulation is required and that requires regular maintenance, replacement, inspection etc., such as probes for corrosion monitoring, are to be insulated with removable insulation. HOLD for final fire loads and verification of insulation thickness for class 5 and 8. Applicable also to all other insulation classes in combination with class 5 and 8.
